UNITED STATES PATENT OFFICE...

EMPSON ATKINSON, OF WOODSTOWN, NEW JERSEY.

COMBINED PLOW AND CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 244,165, dated July 12, 1881. Application filed December 16, 1878.

V a perspective view of my combined plow and cultivator; and Figs. 2, 3, and 4, detached views of parts of the same.

The frame of the implement consists, principally, of two longitudinal beams, A A, and

two transverse beams, B B, preferably of wood, the beams B being supported some distance above the beams A by means of iron or other metal posts a, bent inward, as shown in Figs. 1 and 2, so as to act as lateral braces as well as supports for the beams B. The beams A A are inclined in respect to each other, the distance between them being considerably greater at the rear than at the front ends, and to each beam A, at both the front and rear ends, is hung a block, D, recessed for the reception of a head upon the stem or shank of a plow, F, each block D being enlarged at or near its center f, so that a circular opening may be formed therein of sufficient size to receive the head 11 of the bolt b, by which the block is secured to the beam A, the bolt, of course, being inserted in to its place before the head of the plow-shank has been secured in position within the block. By thus enlarging the block I am 7 enabled to use a single bolt, of such a size that it will possess in itself sufficient strength to serve as a support for the block and plow, in place of the two or more bolts usually employed. The pivoting of the block by a single bolt, moreover, permits it to be more readily adjusted to different positions than a block secured by two or more bolts.

To each beam A, about midway of its length, is secured by a bolt, d,-a beam,Gr, from which project four standards, 0, in the lower ends of which are formed bearings for the shafts of three circular disks or harrows, J, each disk being firmly secured to its shaft, and each shaft being independent of the others,so that while I secure all the advantages of independentlyrotating disks I overcome that clogging of the bearings and sticking of the disks which is an objection to that class of machinesin which the disks turn independently on a single fixed shaft. By adjusting the beams G the angle at which the disks are presented to the soil turned up by the foremost plows, F, may be regulated and the action of the disks on the soil thereby governed.

Secured to each end of the foremost transverse beam, B, is the upper end of a downwardly-projecting plate, 9, which is bent inward at the lower end and secured to the adjacent beam A, near the front end of the same. In each plate 9 are formed a number of openings, i, to either of which may be adapted a pin, m, passing through a box, a, and serving both as a support for the same and as a pivot A for a roller, 8, against the under side of which bears a rod, I, carrying at the front end a whiffletree, m, and connected at the rear to one end of an evener-bar, N, hung to the under side of the rear transverse frame, B. The rollers sserve to permit the easymovement of the rods I, caused by the uneven draft of the horses, while by raising or lowering the boxes in the extent to which the plows are caused to enter the soil may be varied. The plates g, being rigidly secured at both top and bottom to the fixed frame of the machine, are calculated to effectually resist the severe lateral strains to which they are subjected as the horses swerve to one side or the other.

The guiding-handles w 20 extend from one beam B to the other, and project considerably beyond the rear of the frame, the handles serving to brace the beams B longitudinally, in addition to the bracing-rods so, which extend from the rear beam, B, to the beams A A, as shown in Fig. 1.

The above-described implement is simple and cheap in construction,but has been found in practice to be strong and capable of doing its intended work in an effective and expeditious manner, the frame straddling the row, so that the stalks pass between the beams A A and under the beams B B,'tl1e plows and barrows of one beam A thus acting on the soil on 1 two opposite beams, A A, each of which carone side of the row, and the plows and harrows of the other beam A acting on the soil on the opposite side of the row.

I claim as my invention- 1. The combination of the beams A B, the plates g,rigidly secured thereto, and each having a series of openings,i, the rollers 8, adapted to boxes at, and the hanging bolts m, serving both to pivot the rollers and secure the boxes to the plates 9, as specified.

2. A combined plow and cultivator having ries at the front and rear end a plow, F, and at or about the ccnterabeam, G, with a series I 5 of rotating disks or harrows, J, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EMPSON ATKINSON.
